Answer:

contain a mutated tumor-suppressor gene.

Explanation:

  • A tumor suppressor gene performs the function of regulating the proper division of the cells as well as regulating replication.

The tumor suppressor genes perform the following functions :

  1. Maintain the stability of the genome.
  2. Regulate cell growth.
  3. Regulates cell proliferation rate.
  • Whenever the tumor suppressor genes get mutated it would either result in a loss of its function or a reduction in its function which can lead to the abnormal growth of cells.
  • Hence, if the DNA is damaged, the cells become crowded and the nutrients run low then this indicates that the tumor suppressor genes are mutated.
